Today, a post on the Arduino Blog states a limited run of the long awaited Arduino TRE is now available for Beta Testers. 50 “Developer Edition” pre-production boards are available at the hefty price of €149.00 ($204.38 as of today). However, that price gets you:

“not a typical Arduino board. It’s a Linux computer running on a Sitara processor, plus a full Arduino Leonardo. It builds upon the experience of both Arduino and BeagleBoard.org, combining the strengths of both.”

You’ll also have input in the final production version. The testing period is scheduled to be about 3 months and the final version should be out later this year.
